Catalogues#

In Roseau Load Flow, some classes are provided with a catalogue. This page describes how to use them.

Networks#

Roseau Load Flow is provided with a small catalogue of MV and LV networks. These networks are available through the class ElectricalNetwork.

Here is an interactive plot to explore them. See the Plotting page to learn how to get such interactive map.

Source of data#

All these networks are built from open data available in France. The complete model of the French distribution network can be provided on demand. Please email us at contact@roseautechnologies.com.

Inspecting the catalogue#

This catalogue can be retrieved in the form of a dataframe using:

>>> from roseau.load_flow import ElectricalNetwork
>>> ElectricalNetwork.get_catalogue()

There are MV networks whose names start with “MVFeeder” and LV networks whose names with “LVFeeder”. For each network, there are two available load points:

  • “Winter”: it contains power loads without production.

  • “Summer”: it contains power loads with production and 20% of the “Winter” load.

The arguments of the method get_catalogue can be used to filter the output. If you want to get the LV networks only, you can call:

>>> ElectricalNetwork.get_catalogue(name="LVFeeder")

Getting an instance#

You can build an ElectricalNetwork instance from the catalogue using the class method from_catalogue. The name of the network and the name of the load point must be provided:

>>> en = ElectricalNetwork.from_catalogue(name="LVFeeder38211", load_point_name="Summer")
<ElectricalNetwork: 6 buses, 5 branches, 8 loads, 1 source, 1 ground, 1 potential ref>

In case no or several results match the parameters, an error is raised:

>>> ElectricalNetwork.from_catalogue(name="LVFeeder38211", load_point_name="Unknown")
RoseauLoadFlowException: No load points for network 'LVFeeder38211' matching the query (load_point_name='Unknown')
have been found. Please look at the catalogue using the `get_catalogue` class method. [catalogue_not_found]

Transformers#

Roseau Load Flow is provided with a catalogue of transformer parameters. These parameters are available through the class TransformerParameters.

Note

Currently, only three phase MV/LV transformers are in the catalogue.

Source of data#

The available transformers data come from the following data sheets:

Pull requests to add some other sources are welcome!

Inspecting the catalogue#

This catalogue can be retrieved in the form of a dataframe using:

>>> from roseau.load_flow import TransformerParameters
>>> TransformerParameters.get_catalogue()

The following data are available in this table:

  • the id: a unique id among the catalogue.

  • the manufacturer: two manufacturers are available. "SE" stands for “Schneider-Electric” and "FT" stands for “France Transfo”.

  • the product range which depends on the manufacturer

  • the efficiency class of the transformer

  • the type of the transformer.

  • the nominal power, noted sn.

  • the primary side phase to phase voltage, noted uhv.

  • the secondary side phase to phase volage, noted ulv.

The get_catalogue method accepts arguments (in bold above) that can be used to filter the returned table. The following command only retrieves transformer parameters of transformers with an efficiency of “A0Ak”:

>>> TransformerParameters.get_catalogue(efficiency="A0Ak")

Among all the possible filters, the nominal power and voltages are expected in their default unit (VA and V). You can also use the Pint library to express the values in different units. For instance, if you want to get transformer parameters with a nominal power of 3150 kVA, the following two commands return the same table:

>>> TransformerParameters.get_catalogue(sn=3150e3) # in VA by default

>>> from roseau.load_flow import Q_

Getting an instance#

You can build a TransformerParameters instance from the catalogue using the class method from_catalogue. You must filter the data to get a single transformer. You can apply the same filtering technique used for the method get_catalogue to narrow down the result to a single transformer in the catalogue.

For instance, these parameters filter the catalogue down to a single transformer parameters:

>>> TransformerParameters.from_catalogue(efficiency="A0Ak", type=r"^y.*$")
TransformerParameters(id='SE_Minera_A0Ak_50kVA')

The id filter can be directly used:

>>> TransformerParameters.from_catalogue(id="SE_Minera_A0Ak_50kVA")
TransformerParameters(id='SE_Minera_A0Ak_50kVA')

In case no or several results match the parameters, an error is raised:

>>> TransformerParameters.from_catalogue(manufacturer="ft")
RoseauLoadFlowException: Several transformers matching the query (manufacturer='ft') have been found:
'FT_Standard_Standard_100kVA', 'FT_Standard_Standard_160kVA', 'FT_Standard_Standard_250kVA',
'FT_Standard_Standard_315kVA', 'FT_Standard_Standard_400kVA', 'FT_Standard_Standard_500kVA',
'FT_Standard_Standard_630kVA', 'FT_Standard_Standard_800kVA', 'FT_Standard_Standard_1000kVA',
'FT_Standard_Standard_1250kVA', 'FT_Standard_Standard_1600kVA', 'FT_Standard_Standard_2000kVA',
'FT_Standard_Standard_2500kVA', 'FT_Standard_Standard_3150kVA'. [catalogue_several_found]

or if no results:

>>> TransformerParameters.from_catalogue(manufacturer="unknown")
RoseauLoadFlowException: No manufacturer matching 'unknown' has been found. Available manufacturers
are 'FT', 'SE'. [catalogue_not_found]

Lines#

Roseau Load Flow is provided with a catalogue of line parameters. These parameters are available through the class LineParameters.

Source of data#

The available lines data are based on the following sources:

The following data are available in this table:

  • the name. A name that contains the type of the line, the material of the conductor, the cross-section area, and optionally the insulator type. It is in the form {line_type}_{conductor_material}_{cross_section}_{insulator_type}.

  • the line type. It can be "OVERHEAD", "UNDERGROUND" or "TWISTED".

  • the conductor material. See the ConductorType class.

  • the insulator type. See the InsulatorType class.

  • the cross-section of the conductor in mm².

in addition to the following calculated physical parameters:

  • the resistance of the line in ohm/km.

  • the reactance of the line in ohm/km.

  • the susceptance of the line in S/km.

  • the maximal current of the line in A.

The get_catalogue method accepts arguments (in bold above) that can be used to filter the returned table. The following command only returns line parameters made of Aluminum:

>>> LineParameters.get_catalogue(conductor_type="al")

When filtering by the cross-section area, it is expected to provide a numeric value in mm² or to use a pint quantity.

Getting an instance#

You can build a LineParameters instance from the catalogue using the class method from_catalogue. You must filter the data to get a single line. You can apply the same filtering technique used for the method get_catalogue to narrow down the result to a single line in the catalogue.

For instance, these parameters filter the results down to a single line parameters:

>>> LineParameters.from_catalogue(line_type="underground", conductor_type="al", section=240)
LineParameters(id='U_AL_240')

Or you can use the name filter directly:

>>> LineParameters.from_catalogue(name="U_AL_240")
LineParameters(id='U_AL_240')

As you can see, the id of the created instance is the same as the name in the catalogue. You can override this behaviour by passing the id parameter to from_catalogue.

In case no or several results match the parameters, an error is raised:

>>> LineParameters.from_catalogue(name= r"^U_AL")
RoseauLoadFlowException: Several line parameters matching the query (name='^U_AL_') have been found:
'U_AL_19', 'U_AL_20', 'U_AL_22', 'U_AL_25', 'U_AL_28', 'U_AL_29', 'U_AL_33', 'U_AL_34', 'U_AL_37',

RoseauLoadFlowException: No name matching 'unknown' has been found. Available names are 'O_AL_12',
